Hello there, my name is Professor Thermostat. I'm here to help you take control.

Let’s have a look round a typical house, and see what controls are in place. Let's start in the living room…

Professor Thermostat

Here’s the room thermostat. Do you have this in your house? 8 million homes in the UK don't have one, but they are important to control temperature accurately. Find out more: modern controls such as a Honeywell room thermostat could help you save £120 a year!

Wireless controls make it much easier to improve heating efficiency. They can be added to almost any system, in any room, with the absolute minimum of fuss, mess and disruption. Watch the video.

Cool for cats

Heating your home while you're out is great for pets but wastes your money. 84% of household energy consumption is generated through heating and hot water, so it pays to take control. Programmed On/Off heating periods, rather than having heating on 24/7 will have a great effect. Find out more

Too hot?

Opening a window to cool down is akin to throwing money out of it. To stay comfortable and financially better off, simply turn down your thermostat by a degree or two. Find out more

Ensure that Thermostatic Radiator Valves (TRVs) fitted in the same room as the room thermostat are turned up to maximum – otherwise the boiler will always be firing, as the set temperature will never be reached. Read more.
